I guess "nAvgBytesPerSec" is the value for the perfect buffer lenght!!

so I a set this structure for the WAVEFORMATEX:

wf.wBitsPerSample = 16;
wf.nChannels = 1;
wf.nSamplesPerSec = 44100;
wf.nBlockAlign = (wf.nChannels * wf.wBitsPerSample) / 8;
wf.nAvgBytesPerSec = (wf.nSamplesPerSec * wf.nBlockAlign);

"nAvgBytesPerSec" will be: 88200 !!! that's the perfect buffer!!!

thanks!!
